At this time, it will be understood 40 Fig. 3 is a bottom plan view of the cap which that various methods of governing the placement I employ. of the cap in one position with respect to the Fig; 4 is a plan view of the guard plate shown uard pl y be mpl y The raz r blad in Figs. 1 .and 2. 20 includes a central opening 28 for receiving the 5 Fig. 5isaview similar to'Fig. 4 showingamodstud I4 and has two other apertures 29 having ification. radial cuts 30 to permit the mounting of the Fig. 6 is a longitudinal section through the blade in two different positions upon the rib razor showing the modification in Fig.5; and, pin 23a.

Fig. 7 is a plan view of the razor blade which The construction shown in Fig. 5 of the draw- 3 I employ. v ing differs from that shown in Fig. 4 simply in In the accompanying drawing, It represents a eliminating the diagonal arrangement of the ribs handle member upon which a guard plate has l8, and in providing the central portion of the a swivel mounting as is'indicated at l2, the upguard plate lid with a large recess 31 on the per end of the handle member having a threaded upper surface thereof and having the ribs 18a 5 bore I3 to receive the central threaded stud I over the guard finger Na and the intermediate i grooves lfla open into the recess 3|, and the ribs l8b intermediate the guard fingers Na and the recesses 19b in alinement with the guard fingers Ila enter into said recess 3|. The large recess 3| will place the recesses I9a, l9b in communication with each other to permit the clearing out of lather in the use of the razor just as readily as in the construction shown in Fig. 4 of the drawing.

In the use of the razor it will be understood that the edge 20a disposed above the guard fingers I] being free, will permit the performance of the first shaving operation in a quick, comfortable and assured manner, whereas the second or close shave may be performed with greater safety and assurance by the edge 20b disposed above the guard fingers l6.

By providing a razor of the class described, the user may perform the desired shaving operations more successfully, regardless of the characteristics of the skin or hair being shaven and twofold uses of the razor are provided. In this connection, it will be apparent that in some extreme cases, a user may find it desirable to use in some instances only one edge, but the holder is such as to adapt the razor for any and all uses and to suit the desires of all.

It will be understood that while 1 have shown certain details of construction for carrying my invention into effect, I am not necessarily limited to these details and various changes in and modifications of the construction herein shown and described may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
